Description of the Related Art A safety pipe joint provided on an oil supply hose of a weighing machine has been proposed by the present applicant in Japanese Patent Laid-Open No. 2-107890. In this safety pipe joint, since the valve body is provided only on one pipe joint, there is a disadvantage that oil flows out from the other pipe joint side where the valve body is not provided when the safety pipe joint is separated. Further, a safety pipe joint in which a valve body is provided on both pipe joints is also proposed by the present applicant in JP-A-60-188689. In this safety pipe joint, the valve bodies are provided on both pipe joints, but since the valve bodies are only abutted against each other, the position of the valve body is unstable, and the flow of oil causes the valve body to move. There is an inconvenience that the valve opening varies.
